Biosynthesis of ambiguine indole alkaloids in cyanobacterium Fischerella ambigua.
Hillwig M.L., Zhu Q., Liu X.
Ambiguines belong to a family of hapalindole-type indole alkaloid natural products, with many of the members possessing up to eight consecutive carbon stereocenters in a fused pentacyclic 6-6-6-5-7 ring scaffold. Here, we report the identification of a 42 kbp ambiguine (amb) biosynthetic gene clus ... >> More
Ambiguines belong to a family of hapalindole-type indole alkaloid natural products, with many of the members possessing up to eight consecutive carbon stereocenters in a fused pentacyclic 6-6-6-5-7 ring scaffold. Here, we report the identification of a 42 kbp ambiguine (amb) biosynthetic gene cluster that harbors 32 protein-coding genes in its native producer Fischerella ambigua UTEX1903. Association of the amb cluster with ambiguine biosynthesis was confirmed by both bioinformatic analysis and in vitro characterizations of enzymes responsible for 3-((Z)-2'-isocyanoethenyl) indole and geranyl pyrophosphate biosynthesis and a C-2 indole dimethylallyltransferase that regiospecifically tailors hapalindole G to ambiguine A. The presence of five nonheme iron-dependent oxygenase coding genes (including four Rieske-type oxygenases) within the amb cluster suggests late-stage C-H activations are likely responsible for the structural diversities of ambiguines by regio- and stereospecific chlorination, hydroxylation, epoxidation, and sp(2)-sp(3) C-C bond formation. << Less

In vitro stepwise reconstitution of amino acid derived vinyl isocyanide biosynthesis: detection of an elusive intermediate.
Chang W.C., Sanyal D., Huang J.L., Ittiamornkul K., Zhu Q., Liu X.
In vitro reconstitution of a newly discovered isonitrile synthase (AmbI1 and AmbI2) and the detection of an elusive intermediate (S)-3-(1H-indol-3-yl)-2-isocyanopropanoic acid 1 in indolyl vinyl isocyanide biogenesis are reported.

In vitro reconstitution of a newly discovered isonitrile synthase (AmbI1 and AmbI2) and the detection of an elusive intermediate (S)-3-(1H-indol-3-yl)-2-isocyanopropanoic acid 1 in indolyl vinyl isocyanide biogenesis are reported. The characterization of iron/2-oxoglutarate (Fe/2OG) dependent desaturases IsnB and AmbI3 sheds light on the possible mechanism underlying stereoselective alkene installation to complete the biosynthesis of (E)- and (Z)-3-(2-isocyanovinyl)-1H-indole 2 and 5. Establishment of a tractable isonitrile synthase system (AmbI1 and AmbI2) paves the way to elucidate the enigmatic enzyme mechanism for isocyanide formation. << Less
